The 3 phone edit is like a phone company real life nightmare I had. I couldn't reach a 1-800 toll free business phone, so I dialed the area code number,which I had to pay for. I got nowhere after calling six different numbers. It's like the government. Nobody was in charge. It's somebody else at a different number.
Not only was the problem not solved, AT&T called me to say "thank you. your problem has been solved."
Whatever it was, the 1-800 number finally mysteriously fixed itself several weeks later. That was a minor problem. So if your phone works at all, be happy, don't worry.
